Your mouth can reveal early signs of health issues, so persistent changes shouldn’t be ignored. White or red patches, sores that last longer than two weeks, bleeding gums, chronic bad breath, or changes in tongue color or texture can point to problems ranging from vitamin deficiencies and infections to gum disease or more serious conditions. Early dental or medical checks can catch issues before they worsen.
Cold sores deserve special attention. Caused mainly by the herpes simplex virus (HSV-1), they’re contagious and often start with tingling before painful blisters appear. Stress, illness, sun exposure, or a weakened immune system can trigger outbreaks. While there’s no cure, antiviral medications, topical treatments, and good hygiene can shorten outbreaks and reduce spread. See a doctor if sores are frequent, severe, spreading, or interfering with daily life.
